Abstract

In unserem Beitrag stellen wir eine Drohne vor, welche für eine hochpräzise Kartographie mit Positions- und Orientierungssensoren ausgestattet ist. Der Einsatz der Sensoren als absolute und relative Messung kann die Genauigkeit des Mappings erhöhen, falls die Sensoren korrekt kalibriert sind. Dies zeigen wir an einem Fallbeispiel, in dem eine Blockstruktur beflogen wurde, in welcher Passpunkte (Ground Control Points) nur lokal angelegt wurden. Eine redundante Sensor-Konfiguration zeigt dann auf, wie gut und genau die Kalibrierung und dessen Resultat sind.

Inertial measurement unit

An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the orientation of the body, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. When the magnetometer is included, IMUs are referred to as IMMUs. IMUs are typically used to maneuver modern vehicles including motorcycles, missiles, aircraft (an attitude and heading reference system), including unmanned aerial vehicles (UAVs), among many others, and spacecraft, including satellites and landers.

Dead reckoning

In navigation, dead reckoning is the process of calculating the current position of a moving object by using a previously determined position, or fix, and incorporating estimates of speed, heading (or direction or course), and elapsed time. The corresponding term in biology, to describe the processes by which animals update their estimates of position or heading, is path integration. Dead reckoning is subject to cumulative errors.

Mobile robot

A mobile robot is an automatic machine that is capable of locomotion. Mobile robotics is usually considered to be a subfield of robotics and information engineering. Mobile robots have the capability to move around in their environment and are not fixed to one physical location. Mobile robots can be "autonomous" (AMR - autonomous mobile robot) which means they are capable of navigating an uncontrolled environment without the need for physical or electro-mechanical guidance devices.
